Ok, this will be a pain in the ass, I think, giving us more problems than it solves:
"When you move a zone, you can’t move it through a solid obstacle."
So when I have a column that block 1x1 square I can't move the zone couse it's blocked? fog can be tricky I see
That gives me another question. Can I crate zone if some of it space will be on tree, colum or a wall squares?
